Andreas Rheinhardt 1889e3166c libavformat/mux: Fix audio_preload Commit `31f9032b` added the audio_preload feature; its goal is to interleave audio earlier than the rest. Unfortunately, it has never ever worked, because the check for whether a packet should be interleaved before or after another packet was completely wrong: When audio_preload vanishes, interleave_compare_dts returns 1 if the new packet should be interleaved earlier than the packet it is compared with and that is what the rest of the code expects. But the codepath used when audio_preload is set does the opposite. Also fixes potential undefined behaviour (namely signed integer overflow).

libswresample implements audio mixing and resampling routines.
libswscale implements color conversion and scaling routines.

Tools

ffmpeg is a command line toolbox to manipulate, convert and stream multimedia content.
ffplay is a minimalistic multimedia player.
ffprobe is a simple analysis tool to inspect multimedia content.
Additional small tools such as aviocat, ismindex and qt-faststart.
